摘要:
Methods of operating fuel injectors with intensified fuel storage. At least one storage volume is provided in the intensifier type fuel injector, with a check valve between the intensifier and the needle chamber and storage volume preventing loss of injection pressure while the intensifier plunger cylinder is refilling with fuel. Using the check valve to isolate the storage volume from the intensifier to reduce and control pressure spikes that effect injector operation. This provides very efficient injector operation, particularly at low engine loads, by eliminating the wasted energy of compressing, venting and recompressing fuel for injection and reducing and controlling pressure spikes that effect injector operation.
摘要(中):
操作具有加强燃料储存的燃油喷射器的方法。 在增压型燃料喷射器中提供至少一个存储容积,在增压器和针室之间具有止回阀,并且在增压器柱塞缸重新填充燃料时防止了注射压力的损失。 使用止回阀将储存容积与增压器隔离,以减少和控制影响注射器运行的压力峰值。 这提供了非常有效的喷油器操作,特别是在低发动机负载下,通过消除压缩,排气和再压缩注射燃料的浪费的能量,并且减少和控制影响喷油器操作的压力尖峰。
